Greenback 16ohm

Replaced my stock 1960 Marshall cab celestion speakers with four of these. Great tone.. Great move.. DO NOT SETTLE FOR LESS.. Get the Marshall cabs with these factory installed.. If it's too late like it was for me. Get these. Astonishing improvement. Better than my V30 loaded cab hands down!

Huge difference!!

Put this on a 1x12 epiphone valve junior cab to replace the Emminence Lady Luck stock speaker and what a difference....have since plugged in other amps to that cab and I can hear and feel the upgrade. I play Blues/rock and it is so nice to crank it now! Thank you Nich Magnani for your advise and professional support!!

I have a VHT Special 6 Amp and cabinet and it rocks with this speaker lows, mods, and high gain are great a whole new different sound. The punch and crunch are controllable with ease, the best PMP.
